MOLI) PARTITION.

Application filed September 10, 1923. Serial N0. 661,843.

This invention is clirected to a novel ancl unique for1n of artition aclaptecl to be usecl in ce1nent molcling machines und more especially those machines aclaptecl for the casting 01 molcling of louilrling blocks The machines in which the invention is aduptecl for use 1nay be the well known gang molds molcl cavities in euch of which a block is cast.

Tho invention is intencled primarily to j cast a block dcscribecl und clairnecl in xny ap plication 011 builcling block filed on even dato herewith ancl Will be describecl in this use.

It l1as been heretoforecommon to use partitions to divicle the ma in molcl chamber intoj In its preferrecl practical form, the par tition of the present invention is constructecl from sheet o1 cast metal ancl its opposite sicles are complementary to one another with its longitudinal cross section a duplication of its transverse oross section both in shape and proportions. This shaping und. proportioning of the partition imparts to it the function statecl, namely, ics ability to molcl a block aclaptecl for substantially universal use.

Features of the invention, other than those aclvertecl to, Will loe apparent fro1n the hereinaftcr cletailecl description ancl clai1ns, When reacl in conjunction with the accompanying clrawings.

Thc accompanying drawings illustrate cliiferent practical emloodiments of the invention, but the constructions therein shown are to be understood as illustrative, only, ancl not as clefining ehe, li1nits of the invention. 1gure 1 is a perspective view of the partit10n emboclying the present invention.-

F1gure 2 is a longitudinal section on tl1c line .22 of F igu1e l. A

Figu1e 3 is a sction ol three blocks such as woulcl be cast between two such partitions as shown in F igu1e l. In Figure 8, one of the blocks is shown in co1nplete section, while theotbtzr two are shown in frag mental section.

Figure 4 is a perspeotive view of a cored Partition; und,

Figure 5 is a section,of a corecl block resulting from thc use 0f partitions such as shown in Figure 4.

Referring first to Figurcs l3, the partition is shown as constructecl l:'rom sheet or c ast n1etal, preferably cast iron,;the partition being so macle that its opposite faces alte complementary to oncanother whereloy one -0f its faccs. 1 is adaptecl to cast the lemalc face of a block while its other face 2 is adaptccl to cast the male face of another block. The partition is so configuratecl that its longitudinal section is in the form of multiplies of its transvcrse section und in the sl1owing of the clrawings, the partition is twice as long as it is high und its longi tuclinal section is therelore equal to two transverse sections of tl1e partitions. That is to say, that portion of thc Partition to the left of the center line 3 in Figure 2 is iclentical With that portion of the partition to the right of saicl ccnter line, while euch is iclentical With the transverse section of the partition. In this is the unclerlying feature of the present invention.

In Figule 3, three blocks cast incliviclually octween-two such partitions as have been clescribecl a1e shown. Thc block 4 is shown in ceritral vertical longitudinal section. The block 4:" is shown in the s2une manncr while thc block 4 is shown in transversc section. This view illustrates the lnanncr in Which three blocks 0'f two clifferent courses may cooperate to l011n a corncr tie 01:' the Walls of a builcling, this beingmacle possible by the synnnetrical shaping of the male und formale molcling portions of' the partition. In other Words, by cluplicating the transverse section 0'f the partition in the formation of its longitudinal section, the male und.

female portions Of the resulting block Will naturally be symmetrical so that the blocks of adjacent courses can cooperate Wih one another either in parallel half lappecl relation 01' in half lappecl relation at right angles to one anothcr. This is important from a building stanclpoint since the block becomes a standarcl uni either in a running course 01' als tl1e junction of two Walls o1 als corne1s O1 in pilasters 01 in sin1ilar 100ations where the ende of acljacent blocks 01" the same course abut o1 are exposed.

Tlie invention as shown in Figure 4 differs from tlie showing in Figures l ancl 2 only in the fach tl1at tl1e central portion of the artition is cnt outto pern1it alle assage cf a core thercthrough. l*igu1e 5 shovs the resulting corecl block ancl it will be noted tl1at in all respects, it is "ehe same as tl1e blocks shown in Figure 3 except that it is cored.

WVl1en part1t1ons embody1ng tl1e present 1nvention are usecl m gang 1naclnnes adaptecl to cast a numloer of blocks, a single block Will be cast between each two acljacent partitions though as statecl the invention is not restrictecl to machines otf this character as it can be employecl in machines of the similar type clisclosecl in my copencling application referrecl t0 wherein only two blocks a1e cast at a time, the partition serv- 1ng to cast acljacent faces of the two blocks while the clistant faces of tl1e blocks are formecl in the sicle Walls of the apparatus.

In the preferr ed construction, the partition is twice as long as it is high, but if a longer block is desirecl, i; may oe macle 0f a lcngth three o1 1nore times its height by merely cluplicating its cross sectional shape in the fonnation of its linear section.

The accompanying clrawings show the invention in its preaferred form, but it is t0 be understoocl as fully commensurate with tl1e appendecl claims.

Having thus fully clesciibecl the invention, Whau 1 claim as neW ancl desire 150 secure by Letters Patent is:

l. A molcl artition, the length 0'f Wlli0ll is a multiple oi' its height anal the opposite faces o1 which paiui'ion are complementary to one another with a linear section of the partition a duplication of the transverse section thereof.

2. A molcl artition, the opposite faces of which are coi'nplemen'taiy male and female ancl tl1e longitudinal sectionof which is a duplication of its t1ansverse section, sail artition being twice as long as it is high.

3. A moicl artition substantially twice as long as it is high, one face of saicl artition being proviclecl with project-ing male portions and tl1e opposite face of the partition being proviclecl with c0n1plementary reenurant female portions, all of saicl portions being symmetrical ancl the longitudinal section of' the partition constituting a duplication cf the transverse section thereof.

111 testimony whereof I l1ave signed the forcgoing specification.
